Extracted text: 1. What responses are generated by the nervous system when you run on a treadmill? Include an example of each type of tissue that is under nervous system control. 2. Multiple sclerosis is a demyelinating disease affecting the central nervous system. What type of cell would be the most likely target of this disease? Why? 3. Which type of neuron, based on its shape, is best suited for relaying information directly from one neuron to another? Explain why. 4. Sensory fibers, or pathways, are referred to as "afferent." Motor fibers, or pathways, are referred to as "efferent." What can you infer about the meaning of these two terms (afferent and efferent) in a structural or anatomical context? 5. If a person has a motor disorder and cannot move their arm voluntarily, but their muscles have tone, which motor neuron-upper or lower-is probably affected? Explain why.
